IMPROVEMENT IN REAPING-MACHINES.

To all whom it may concern:

Be it known `that I, J. B. MoCoRMIcK, of St. Louis, in the county of St. Louis and State ot' Missouri, have invented a new and Improved Grain-Discharging Device for Harvesttrs; and lI do hereby declare that the following is afull,clear,and exact description ofthe same, reference being had to the accompanying drawings, making a. part 'ot this vspecification. in whiehy Figure 1 is a side sectional view of my invention, taken in the line a' rv, Fig. 2; Fig. 2, a plan or top view ofthe same.

Similar letters of reference indicate correspondingparts in the two iigures.

This invention consists in the employment or use of an automatic rakearranged to op` crate in such a manner as to deliver the grain at one side of the rear of the machine, in combination with a gavel-receivng table anda binders7 platform or stand, all arranged as here proceed to describe it.

A represents the main frame ol a reaper, and B the platform.' The front part of the main frame is supported by a. pair of truckv wheels, G C, and in said frame thereisa driving-wheel, D, which is its chief support, and drives the working or operating parts. The grain end of the platform is supported by a wheel, E, commonly termed the grain-wheel. This wheel E also supports the corresponding end ot' the linger-bar and reel, and it is attached to a iirm bar, a", which is permanently secured at right angles to the back bar of the main frame. f

The platform B properthat is to say, the part on -which the grain falls-is so arranged and attached to its framing as to leave-a space 'or groove, c, all around it, and in this space or groove tt a cord, F, works, said cord passing around pulleys I) at each corner or angle of the platform. One of these pulleys b has a bevel-wheel, c, at its under side,and the wheel c gears into a corresponding` wheel, d, on a shaft, e, which receives its motion through the medium ot' gears f from the axle of the driving-wheel D. The framing to which the platform B is attached isa swinging one, and is composed ofa series of bars, bX to thefrontends of which the finger-bareX is attached. The back A. I i

ends ofthe bars' b* are secured to the main frame A by means of pivots, which are in line with the shaft e, the latter having its bearings in the platform-frame. On the shaft e there is placed a beyel-wheel, cX X, which gears into a. bevelpinion, dx, at the back end ot' a shaft, ex, the front end of which has a crank-pulley,f", attached to it, from which the sickle is driven bya con necting-rod. The back end ofthe shaft c has its bearingin a boX, (/",whichisofloop form, to admit of the bevel-pinion ZX working within it,and this box g* is attached to aplate or bar, hl, which is fitted ou the shaft e, as shown in Fig.2. By thisarrangementit will be seen that the nger-bar maybe raised and lowered without affecting the main frame or interferingin the least with the sickle-driving mechanism. This result is attained by having the pivots which connect the back end of the platform-frame to the main frame in line with the shaft c.

t The front part of the front platform-frame has two diagonal rods, 12X tx, attached, which extend forward and upward toward the front part of the main frame A, and directly over the truck-wheels C C. The front ends of the rods i* i* are attached to the ends of cranks jVK jx on a shaft, 70X, to which a lever, l", is secured, said lever being provided with a sliding dog, mx, which is actuated by a spring, nx, and lever 0X, thespring n* havinga tendency to keep the dog engaged with a toothed segment-plate,p, attached to the side of the main frame. By actuating the lever lx it will be seen that the front part of the platfornr.

frame maybe raised and lowered, and retained at any desired point by the dog mx., thelatt-er being disengaged from the toothed segmentplate o* when it is desired to adjust the sickle by actuating` the lever 0X.

G is a rake, the arm gof which passes loosely through a swivel-pin, h, at the outer end of abar, H. The rake rests on theplatt'orm, and is connected by a pin, i, to the cord F, and as the machine is drawn along works over the platform in the direction indicated by the arrows n Fig. 2, and discharges the'grain at one side ot' the rear of the platform and upon a table, I, which .is attached to the framing at theback of the platform.

J represents a binders stand or platform, which is suspended byrodsj from the framing of the machine, and is directly below the table I. The hinders stand ou this platform and vThe automaticrake G, arranged to operate take the gavel from the table I, bind them,"and so as to discharge the grain alt one sid@J of the discharge them upon the ground. rear of the platform B,iu combination with the The reel K is driven from the axle of wheel table I a-nd binders platform or stand J, all D through the medium of al belt, L. arranged substantially as herein set forth.

l do not claim separately the rake G, 0perarmi as shown, for that has been previously J'. B. MCGORMIGK.
